PROPI-:LLING MECHANISM FOR BOATS.`

SPECIFICATIQN forming part of Letters Patent No. 509,133, dated November 21, 1893. Appnmion fired April 28,1895. serial No. 472,191. (No model.)

To @ZZ whom it may concern: f

Be it known that I, JOHN R. MAHONEY, a citizen of the United States, residing at Sistersville, in the county of Tyleraud State of West Virginia, have invented Ycertain new and useful Improvements in Propelling Mechanism for Boats; and I do declare the following to be a full, clear, and exact description of the invention,such as will enable Others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forni a part of this specification.

The special object of the invention is to make a propellerwhich may be operated'and steered by one person, the boat being of shallow draft and requiring a small power to carry it along through the water.

Figure 1 of the drawings is a plan view; Fig. 2 a median longitudinal section, and Fig. 3 a transverse vertical section. Y I

In the drawings, A represents the body of the boat having the flat bottom a, the sharp prow a', sides a2 a2 and stern a3, the latter being preferably made to incline outwardly from the bottom upward.

B is the boatmans seat supported ou two parallel walls or board uprights C C in which is journaled a crank or pedal shaft D made fast to the drive wheel E between said walls. Sitting on the seat B, the boatman rotates the crank shaft D with his feet and turns the spurwheel E which gears with a spurwheelh` on the shaft G and fast to the middle thereof. The wheel F rotates shaft G- and its fastendwheel H which turn the end wheels I I on the propeller J. Of course, I may' use sprocket chain and wheels or belts and pulleys instead of spurgears to connect the driveshaft with the propeller, as they are well known operative mechanisms.

The stern wheel propellerJpmay have two or more radial paddlesj, but I prefer four as shown in the drawings. The shafts I) are journaled in or on the sides a2 ai while the propeller shaft is journaled in an extension thereof beyond the rear of the boat.

K is the steering post with the radial handles 7e at top andthe pinion L at the bottom. This pinion reciprocates in either direction, the rackbar M between the two guides N N, the said rackbar being connected by the ropes O O with the rudder plates P, P, turning on Patent, is-

The boat A having a box seat B at the rear end, a crank-pedal shaft journaled under said seat and carrying in the middle thereof a spur-wheel E, a countershaft G with amiddle pinion F gearing with wheel E and two endpinions H H, and a paddle wheel on a shaft with end-wheels whiehlgear with the pinions H H, as and for the purpose setV forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN H. MAHONEY.
